Question

Is every equilateral triangle isosceles? Is every isosceles triangle equilateral? Explain your thoughts.

Answer 1

Every equilateral triangle is isosceles, but not every isosceles triangle is equilateral. These are both isosceles triangles

an isosceles triangle has to have two or more sides that are equal, that second triangle has a third side that isn't the same as the other two, so it's not equilateral.
